Right now, my first pick would be a black standard poodle. I met one once, in the dark, and when it smiled it scared the holy crap out of me. Glistening white teeth in the dark. Hoooo, still gives me chills to remember that 25 years ago. Then, I'd like a German Shepherd, except for the hair. I also worry about their ability to survive harsh weather; that's why I keep coming back to the shepherd.
